PRISONER RIGHTS ARE HUMAN RIGHTS

New analysis of prisoner healthcare highlights risks to patient safety


SAGE

Substantive changes are needed to improve patient safety in prisons, according to a new study published by the Journal of the Royal Society of Medicine (JRSM) and funded by the National Institute for Health and Care Research (NIHR). Practical changes such as timely access to healthcare services and better processes to mitigate medication-related harm should be prioritised, according to the researchers.

In the first nationwide analysis of patient safety incidents in prisons in England, researchers found that security, staffing constraints and the high turnover of prisoners are among the main barriers to the safe delivery of healthcare in prisons. They made several recommendations for how prison and healthcare leaders can work together in the interests of better coordinated and safer care.

The authors, from Cardiff University, the University of Manchester and the University of Nottingham, reviewed more than 4,000 reports from prisons across a whole year, where a patient could have, or did, come to harm.

A third of cases were related to medication – for example, patients missing doses of prescribed medication or given the wrong treatment. Staff mistakes, such as mixing up similar patient names, were the most common reasons cited, and over 20% of medication-related reports were discovered and mitigated by staff, preventing any harm to patients.

In three out of 20 reports, prisoners were delayed in accessing or unable to access healthcare, including appointments at external hospitals. Security barriers, such as when prison wings are on lockdown, and lack of staff were the biggest causes identified by the researchers, with changes to escalation policies required to prevent this and more support needed for prisons to maintain safe staffing levels.

They noted that prisoners use healthcare services three times more frequently than the general population, with poorer health outcomes. “Healthcare priorities are often overshadowed by a prison’s main objective of securing detained individuals,” the authors wrote. The risk of this is that the healthcare and criminal justice systems are out-of-sync to “adequately consider prisoner needs and responsibility of care”.

The researchers suggested that reviewing staff rotas, improving training and rethinking prison layouts could help improve access to in-house care. For external hospital appointments, they recommended revised escalation policies and plans to ensure staff escorts are put in place, and increased use of remote appointments and ‘in-reach’ clinics. Standard handover practices, policies to ensure the safe transfer of medication and prescription information, and appropriate discharge planning could help to ensure continuity of care when people transfer in or out of a prison.

The study was funded by the National Institute for Health and Care Research (NIHR) Policy Research Programme (PR-R20-0318-21001). The views expressed are those of the author(s) and not necessarily those of the NIHR or the Department of Health and Social Care.


Hamilton inmate behind growing hunger strike says 'broken system' to blame for poor jail conditions

Story by Bobby Hristova • CBC
 Apr 20, 2023

The inmate who started a hunger strike at Hamilton's Barton Street jail this week said staffing issues and a broken system are behind deteriorating conditions at the detention centre.

"It's sickening ... lives are at stake," Jesse Bull told CBC Hamilton in a phone interview Thursday.

The strike started Wednesday morning amid what inmates say are constant lockdowns, a lack of outdoor time and the fear they may lose access to specialty TV channels.

The maximum-security jail's official name is the Hamilton-Wentworth Detention Centre.

Cedar Hopperton, a volunteer with the Barton Prisoner Solidarity Project, said Thursday the number of inmates striking is now roughly 180.
 
'No extra guards at all:' inmate

Bull said that in the last two months, he's only been able to access the yard and breathe fresh air once, due to a lack of staff.

"If one guard doesn't show up that day for work ... we get no yard," he said.

"There are no extra guards at all."

Andrew Morrison, a spokesperson for the Ontario Ministry of the Solicitor General, told CBC Hamilton that a maintenance project in the yard limited time outside, but a "regular yard schedule" has resumed.

However, Bull said, outdoor time was an issue even before the construction work began.

Bull said lockdowns are another issue. He said they result in three people being held together in a cell, despite there only being enough room for one.

Hopperton previously said some lockdowns have lasted three days.

While in lockdown, inmates aren't given access to hot water or jugs to urinate in either, according to Bull.

"Whenever we get locked down, it's just a staffing issue ... it's not because we're fighting or drinking," he said.

"To be three in a cell, eating where you use the bathroom, being locked down in a hot cell in the middle of summer — no."

Morrison said there were lockdowns at the jail over the past week, but he did not confirm their length of time or whether they have become more frequent.

He said lockdowns are done for multiple reasons, including security incidents, searches, infectious disease control, staff absences, maintenance and other issues.

"Where possible, partial lockdowns are always preferred to continue visitations, showers and inmate programs," the Ministry of the Solicitor General spokesperson said.

Inmate blames system, not staff

Access to mail has also been an issue, and administration is restricting who inmates can write to, according to Bull.

"It's against our rights," said Bull, adding he has been in jail for 20 months for drug-related charges.

He said he was told that administration would look into those issues.

Morrison said inmate mail is "routinely screened for security purposes" and delivered to inmates after clearing security protocols.

Bull said that during his time in jail, he's only been able to exchange his blanket to be cleaned only and gets new sheets once a month if he's lucky.

He said the workers themselves aren't at fault. In fact, Bull said, they're "great." Instead, he blames the broader system.

"There are solutions to this and everybody just doesn't give a f--k," Bull said.

"I just feel like this is one of those situations that will never get solved ... it's a broken system."

Morrison said ministry staff work hard daily to provide care to the inmates.

"The ministry has confidence in the staff and management at the Hamilton-Wentworth Detention Centre to continue to provide support and secure custody to inmates during their incarceration."

Bull also said he has a message for people who say the inmates deserve to stay in deteriorating conditions — don't make snap judgments about prisoners.

"There are so many guys in here that have so much talent, who are highly intelligent, artistic, who have families and jobs and made a wrong turn somewhere," he said.

"People are forgetting humanity ... I really feel with every fibre in my being this needs to be taken care of at a higher level than just jail administration ... we're people too."

Accelerated Christian Education textbooks used in UK schools deny human-caused climate change

Peer-Reviewed Publication

UNIVERSITY COLLEGE LONDON

UCL Press Release
Thursday 18th May,

Peer reviewed | Literature review | People

One of the world’s largest fundamentalist Christian education groups is teaching its students climate change denial as fact, and still presents the theory of evolution as an ‘absurd and discredited’ conspiracy theory, finds a report by UCL researchers.

Accelerated Christian Education (ACE) is one of the world’s biggest providers of creationist science materials, consisting of reading programmes and a core curriculum, for thousands of affiliated schools worldwide, including dozens across the UK and Europe.

There are currently 11 schools in England and Northern Ireland officially affiliated with ACE, although experts expect there to be many more as the schools are notoriously isolationist, conservative and don’t advertise themselves widely.

In the report, published in Cultural Studies of Science Education, researchers found that its latest edition, which has been released to year groups from Key stages 1 to 3 gradually over the last few years, now claims to show ‘evidence’ that human-caused climate change is not real and still presents evolution as a conspiracy theory. This is despite claims by the curriculum’s developers that its materials allow students to make up their own minds about evolution.

The addition of climate change denial as a proof point for creationism follows on from previous editions which claimed the existence of a ‘vapour canopy’ that surrounded Earth until it burst, causing Noah’s flood. Although the most recent edition doesn’t include this and the claim has largely been dropped by the group, space within the material previously given over to the theory now covers climate change, specifically to deny a human link between rising temperatures and to reassure students of God’s plan in preparing a new heaven and Earth with a better climate.

Lead author Dr Jenna Scaramanga (IOE, UCL's Faculty of Education and Society) said: “It is worrying that the most recent edition of this material not only still promotes creationism as a valid scientific theory, but adds climate change denial to its increasingly anti-science agenda. Students studying at ACE schools or using ACE materials move into mainstream further or higher education ill-equipped to study advanced science or to make informed judgements about scientific discoveries.

“Presenting creationism and evolution in this way is a conspiracy theory, as the providers and teachers argue that mainstream scientists are colluding to promote false ideas. Teaching children in this way means they are more likely to easily accept and believe other conspiracy theories.”

The authors found through analysing the third and fourth editions of the material that younger primary / elementary school children are not exposed to any ideas contrary to ACE’s literal interpretation of the Bible until Year 9, or the eighth grade in the US, around age 13. Researchers say this is contrary to Ofsted education guidance, which stipulates that primary school children must be exposed to a broad and balanced science education.

The fourth edition of ACE’s material was first released for the youngest age group, five- to six-year-olds, in 2009, with subsequent grades following gradually. Material for 12- to 14-year-olds was released in 2016 and 2020 respectively.

Overall, the only substantial difference between the third and fourth editions were two new arguments, which have both been widely discredited by scientists. One is the claim of tiny amounts of polonium found in granite rocks as evidence that Earth formed instantaneously, while the other is that traces of blood vessels and soft tissue found in some dinosaur fossils prove they must have died comparatively recently, suggesting that Earth is a young planet.  

ACE has previously been criticised for relying on rote memorisation over other learning styles and presenting misleading or distorted information. The curriculum delivered within ACE schools regularly includes creationism within non-science lessons and depicts those who believe in evolution as making an immoral choice.

The material has also been previously criticised for supporting white supremacism and defending South African apartheid. In its first 20 years ACE was involved in over 150 lawsuits, mostly relating to accreditation, with subsequent court cases. The company believes that Christian schools should not be regulated, and schools using its curriculum have defended this belief through litigation.

Dr Scaramanga added: “Questions need to be asked about how these schools and those which rely heavily on ACE publications pass Ofsted checks when their curricula and materials clearly fail to provide a broad and balanced science education and fail in the requirement of teaching respect for different beliefs.”

Jenna Scaramanga, Michael Reiss ‘Evolutionary stasis: creationism, evolution and climate change in the Accelerated Christian Education curriculum’ will be published in Cultural Studies of Science Education

GREAT BARRIER REEF GETS STD

Chlamydia-like bacteria discovered in Great Barrier Reef


UNIVERSITY OF MELBOURNE

New research, published in Sciences Advances, has discovered a Chlamydia-like bacteria in corals of the Great Barrier Reef that could help scientists understand the coral microbiome and its potential impact on coral reef health. Led by the University of Melbourne in collaboration with the Australian Institute of Marine Science (Townsville) and the University of Vienna, the research found two kinds of bacterial clusters inside the tissues of coral, including a close relative of the chlamydia-causing bacteria (Chlamydiales), and EndozoicomonasThe study, funded by an ARC Laureate Fellowship, adds another layer of complexity to the understanding of coral reef health. Lead researcher from the Faculty of Science at the University of Melbourne, Dr Justin Maire, said Chlamydiales – a bacterial order that contains the pathogens responsible for chlamydia infections in mammals – has never been described before in corals. “We worked with Chlamydiales specialists Dr Astrid Collingro and Professor Matthias Horn from the University of Vienna, and found that these bacteria steal nutrients and energy from their hosts to survive,” Dr Maire said. “The novel Chlamydiales exhibit many similarities with mammalian pathogens, but we are unsure if they are detrimental or beneficial to corals. There is a possibility that this bacterium gets nutrients and energy from other coral-associated bacteria, and for those of us working to understand coral biology, the possibility that the bacteria living inside coral tissues are interacting with each other is quite thrilling.” Senior author of the study, University of Melbourne Professor Madeleine van Oppen, said the other bacterium discovery, Endozoicomonas is known to be widespread in corals, and is generally considered beneficial due to its ability to produce B vitamins and antimicrobial compounds. “One of the focus areas in my lab is the development of bacterial probiotics for corals, helping to improve their resistance to thermal stress and survival rates caused by climate warming,” Professor van Oppen said. “We still know very little about the functions of coral-associated bacteria, and this new study will help us to figure out whether probiotics are a feasible solution and if bacteria such as Endozoicomonas are best placed to do the job.”

Endangered plant species critical to survival of cultural legacy

Endangered murasaki legacy

Kyoto, Japan -- Purple is a color that has historically been associated with nobility around the world. Japan is no exception. However, its distinct murasaki hue is threatened as the native gromwell plant -- synonymous with murasaki -- has become an endangered species.

Disease and cross-breeding with non-native species are partly to blame for murasaki's growing demise.

Now, a research group including Kyoto University, is leading a movement to raise awareness of gromwell's importance in preserving Japanese culture. For example, murasaki revival projects currently underway throughout Japan are investigating the seed's origins and educating the public on the importance of protecting the plant's homogeneity.

"Various non-profits involved in the revival of gromwell are also keen to maintain the silk staining technique through the collaboration with plant scientists," says lead author Kazufumi Yazaki.

Purple gromwell -- or Lithospermum erythrorhizon -- contains shikonin derivatives in the plant's root surfaces, which are red naphthoquinones.  This natural pigment and medicinal properties are linked to ancient East Asian traditions. Among the range of hues, the most sought dye was the dark purple reserved for members in the top levels of government and the Imperial family, as well as the highest-ranking Buddhist monks.

"The purple color was also used for a national treasure called Koku-Bun-Ji Kyo, the ten-volume Buddhist scripture papers on which letters were written with gold," says co-author Ryosuke Munakata of KyotoU's Research Institute for Sustainable Humanosphere.

For medicinal purposes, the roots are prescribed in several remedies as an ointment called Shi-Un-Koh, which is still popular today in treating hemorrhoids, burns, frostbite, and other wounds.

Recovery initiatives, such as the Mitaka Gromwell Restoration Project, are focused on ensuring the native gromwell's survival, impacted by the spread of cucumber mosaic virus and sudden environmental changes. Cross-breeding with the European species L officinale is another factor in this plant's uncertain future.

Excavated official wooden documents from Kyushu -- found to have been used to transport cargo during the Asuka dynasty -- were unexpectedly related to gromwell, highlighting its purple dye's crucial administrative role.

"We hope our research raises awareness of murasaki's importance in Japanese history and culture," comments co-author Emi Ito of Ochanomizu University.

Before worrying about AI's threat to humankind, here's what else Canada can do

Story by Benjamin Shingler • May 6, 2023

The headlines have been, to say the least, troubling.

Most recently, Geoffrey Hinton, the so-called Godfather of AI, quit his post at Google and warned the rapid advances in artificial intelligence could ultimately pose an existential threat to humankind.

"I think that it's conceivable that this kind of advanced intelligence could just take over from us," the renowned British-Canadian computer scientist told CBC's As It Happens.

"It would mean the end of people."

While such stark comments are impossible to ignore, some experts say they risk obscuring more immediate, practical concerns for Canada.

"Whether deliberately or inadvertently, folks who are talking about the existential risk of AI – even in the negative – are kind of building up and hyping the field," said Luke Stark, an assistant professor of information and media studies at Western University in London, Ont.

"I think it's a bit of a red herring from many of the concerns about the ways these systems are being used by institutions and businesses and governments right now around the world and in Canada."

Stark, who researches the social impacts of technologies such as artificial intelligence, is among the signatories of an open letter critical of the federal government's proposed legislation on artificial intelligence, Bill C27.

The letter argues the government's Artificial Intelligence and Data Act (AIDA), which is part of C27, is too short on details, leaving many important aspects of the rules around AI to be decided after the law is passed.

Look to EU for guidance, experts say

The legislation, tabled last June, recently completed its second reading in the House of Commons and will be sent to committee for study.

In a statement, a spokesperson for Innovation, Science and Economic Development Canada said "the government expects that amendments will be proposed in response to testimony from experts at committee, and is open to considering amendments that would improve the bill."

Experts say other jurisdictions, including the European Union and the United Kingdom, have moved more quickly toward putting in place strong rules governing AI.

They cite a long list of human rights and privacy concerns related to the technology, ranging from its use by law enforcement, misinformation and instances where it reinforces patterns of racism and discrimination.

The proposed legislation wouldn't adequately address such concerns, said Maroussia Lévesque, a PhD candidate in law at Harvard University who previously led the AI and human rights file at Global Affairs Canada.

Lévesque described the legislation as an "empty shell" in a recent essay, saying it lacks "basic legal clarity."

In an interview over Zoom, Lévesque held up a draft of the law covered in blue sticky tabs – each one marking an instance where a provision of the law remains undefined.

"This bill leaves really important concepts to be defined later in regulation," she said.

The bill also proposes the creation of a new commissioner to oversee AI and data in Canada, which seems like a positive step on the surface for those hoping for greater oversight.

But Lévesque said the position is a "misnomer," since unlike some other commissioners, the AI and Data appointee won't be an independent agent, heading a regulatory agency.

"From a structural standpoint, it is really problematic," she said.

"You're folding protection into an innovation-driven mission and sometimes these will be at odds. It's like putting the brakes and stepping on the accelerator at the same time."

Lévesque said the EU has a "much more robust scheme," when it comes to proposed legislation on artificial intelligence.

The European Commission began drafting their legislation in 2021 and is nearing the finish line.

Under the legislation, companies deploying generative AI tools, such as ChatGPT, will have to disclose any copyrighted material used to develop their systems.

Lévesque likened their approach to the checks required before a new airplane or pharmaceutical drug is brought to market.

"It's not perfect — people can disagree about it. But it's on the brink of being adopted now, and it bans certain types of AI systems."

In Stark's view, the Liberal government has put an emphasis on AI as a driver of economic growth and tried to brand Canada as an "ethical AI centre."

"To fulfil the promise of that kind of messaging, I'd like to see the government being much more, broadly, consultative and much more engaged outside the kind of technical communities Montreal, and Toronto that I think have a lot of sway with the government," he said.

'Hurry up and slow down'

The Canadian Civil Liberties Association is among the groups hoping to be heard in this next round of consultations.

"We have not had sufficient input from key stakeholders, minority groups and people who we think are likely to be disproportionately affected by this bill," said Tashi Alford-Duguid, a privacy lawyer with CCLA.

Alford-Duguid said the government needs to take a "hurry up and slow down" approach.

"The U.K. has undertaken much more extensive consultations; we know that the EU is in the midst of very extensive consultations. And while neither of those laws look like they're going to be perfect, the Canadian government is coming in at this late hour, and trying to give us such rushed and ineffective legislation instead," he said.

"We can just look around and see we can already do better than this."


















New use for A.I.: correctly estimating fish stocks

First-ever A.I. algorithm correctly estimates fish stocks, could save millions and bridge global data and sustainability divide

For the first time, a newly published artificial intelligence (AI) algorithm is allowing researchers to quickly and accurately estimate coastal fish stocks without ever entering the water. This breakthrough could save millions of dollars in annual research and monitoring costs while bringing data access to least-developed countries about the sustainability of their fish stocks.

Understanding “fish stocks” – the amount of living fish found in an area’s waters – is critical to understanding the health of our oceans. This is especially true in coastal areas where 90 percent of people working in the fisheries industry live and work. In the wealthiest countries, millions of dollars are spent each year on “stock assessments” – expensive and labor-intensive efforts to get people and boats out into the water to count fish and calculate stocks. That extremely high cost has long been a barrier for tropical countries in Africa and Asia, home to the highest percentage of people who depend on fishing for food and income. Small-scale fishers working coastal waters in many countries are essentially operating blindly, with no real data about how many fish are available in their fisheries. Without data, coastal communities and their governments cannot create management plans to help keep their oceans healthy and productive for the long-term.

Now, thanks to advances in satellite data and machine learning algorithms, researchers have created a model that has successfully estimated fish stocks with 85 percent accuracy in the Western Indian Ocean pilot region. This tool has the potential to get data quickly and cheaply into the hands of local and national governments, so they can make informed decisions about their natural resources and keep “blue foods” on the table.

“Our goal is to give people the information required to know the status of their fish resources and whether their fisheries need time to recover or not. The long term goal is that they, their children, and their neighbors can find a balance between peoples’ needs and ocean health,” said Tim McClanahan, Director of Marine Science at WCS. “This tool can tell us how fish stocks are doing, and how long it will take for them to recover to healthy levels using various management options. It can also tell you how much money you’re losing or can recoup every year by managing your fishery – and in the Western Indian Ocean region where we piloted this tool, it’s no less than $50 to $150 million each year.”

WCS’ McClanahan and fellow co-authors used years of fish abundance data combined with satellite measurements and an AI tool to produce this model. The result? A simple, easy to use pilot tool to better understand and manage our oceans. With further development, anyone from anywhere in the world would be able to input seven easily accessible data points - things like distance from shore, water temperature, ocean productivity, existing fisheries management, and water depth - and receive back an accurate fish stock estimate for their nearshore ecosystems. 

“We know that during times of crisis and hardship, from climate change-induced weather events to the COVID-19 pandemic, people living on the coast increasingly rely on fishing to feed themselves and their families,” said Simon Cripps, Executive Director of Marine Conservation at WCS. “The value of this model is that it tells managers, scientists, and importantly, local communities how healthy a fishery is and how well it can support the communities that depend on it, especially during times of crisis. Once a fishery’s status is known, it gives communities and managers the information to move forward to design solutions to improve fish stocks and improve the resilience of local communities, the fishing industry, and local and national economies.” 

The algorithm has been shown to work with high accuracy for coral reef fisheries in the Western Indian Ocean pilot region. WCS is currently seeking new partnerships and funding to scale the tool so it can be deployed and fill critical data gaps  around the world. 

This work was completed over a number of years and with the support of grants from The Tiffany and Co. Foundation, the John D. and Catherine T. MacArthur Foundation, the Bloomberg Ocean Initiative, the UK Darwin Initiative, and the Western Indian Ocean Marine Science Association’s Marine Science for Management Program (WIOMSA-MASMA).

Integrating IoT, AI, and machine learning for next-generation healthcare

Special topic: Artificial intelligence innovation in remote sensing


Peer-Reviewed Publication

SCIENCE CHINA PRESS

Artificial Intelligence (AI) plays a growing role in remote sensing. In particular, during the last decade there has been an exponentially increasing interest in deep learning research for analysis of optical satellite images, hyperspectral images, and radar images. The main reasons for this interest is the increased availability of a wealthy stream of data coming from different Earth observation instruments and that AI techniques enable a learning-based “data model” in remote sensing. In order to promote research in this area, we have organized a special focus on Artificial Intelligence Innovation in Remote Sensing in SCIENCE CHINA Information Sciences(Vol.66, Issue.4, 2023). Eight papers are included in this special focus as detailed below.

Multimodal remote sensing imagery interpretation (MRSII) is an emerging direction in the communities of Earth Observation and Computer Vision. In the contribution entitled “From single- to multi-modal remote sensing imagery interpretation: a survey and taxonomy”, Sun et al. provide a comprehensive overview on the developments of this field. Importantly, in the paper, an easily understandable hierarchical taxonomy is developed for the categorization of MRSII, further providing a systematic discussion on the recent advances and guidance to researchers in many realistic MRSII problems.

Hyperspectral imaging enables the integration of 2D plane imaging and spectroscopy to capture the spectral diagram/signatures and spatial distribution of the objects in the region of interest. However, ground objects and the reflectance received by the imaging instruments may be degraded, owing to environmental disturbances, atmospheric effects and hardware limitations of sensors. HSI restoration aims at reconstructing a high-quality clean hyperspectral image from a degraded one. In the contribution entitled “A survey on hyperspectral image restoration: from the view of low-rank tensor approximation”, Liu et al. present a cutting-edge and comprehensive technical survey of low-rank tensor approximation toward HSI restoration, with a specific focus on denoising, fusion, restriping, inpainting, deblurring and super-resolution, along with their state-of-the-art methods, and quantitative and visual performance assessment.

Recently, hyperspectral and multispectral image fusion (aimed at generating images with both high spectral and spatial resolutions) has been a popular topic. However, it remains a challenging and underdetermined problem. In the contribution entitled “Learning the external and internal priors for multispectral and hyperspectral image fusion”, Li et al. propose two kinds of priors, i.e., external priors and internal priors, to regularize the fusion problem. The external prior represents the general image characteristics and is learned from abundant sample data by using a Gaussian denoising convolutional neural network trained with additional grayscale images. On the other hand, the internal prior represents the unique characteristics of the hyperspectral and multispectral images to be fused. Experiments on simulated and real datasets demonstrate the superiority of the proposed method. The source code for this paper is available at https://github.com/renweidian.

Wide-beam autofocus processing is essential for high-precision imaging of airborne synthetic aperture radar (SAR) data, due to the absence of inertial navigation system/global positioning system (INS/GPS) data or insufficient accuracy. In the contribution entitled “Wide-beam SAR autofocus based on blind resampling”, Chen and Yu propose a full-aperture autofocus method for wide-beam SAR based on blind resampling. The proposed method does not require INS/GPS data as baseline methods, which can significantly improve the overall image quality. The measured data processing results of the wide-beam SAR verify the effectiveness of the newly proposed algorithm in this contribution.

Remote sensing image (RSI) semantic segmentation has attracted increased research interest during the last few years. However, RSI is difficult in holistic processing for currently available graphics processing units cards on account of large field-of-views (FOVs) of the imagery. Furthermore, prevailing practices such as image down sampling and cropping inevitably decrease the quality of semantic segmentation. In the contribution entitled “MFVNet: a deep adaptive fusion network with multiple field-of-views for remote sensing image semantic segmentation”, Li et al. propose a new deep adaptive fusion network with multiple FOVs (MFVNet) for RSI semantic segmentation, surpassing the previous state-of-the-art models on three typical RSI datasets. Codes and pre-trained models for this paper are publicly available https://github.com/weichenrs/MFVNet.

Change detection of buildings, given two registered aerial images captured at different times, aims to detect and localize image regions where buildings have been added or torn down between flyovers is challenging. The main challenges are the mismatch of the nearby buildings and the semantic ambiguity of the building facades. In the contribution entitled “Detecting building changes with off-nadir aerial images”, Pang et al. present a multi-task guided change detection network model, named as MTGCD-Net, providing indispensable and complementary building parsing and matching information, along with extensive comparisons to existing methods. More importantly, a new benchmark dataset, named BANDON, were created fin this research and it is available at https://github.com/fitzpchao/BANDON.

Photovoltaic devices, a typical new energy source, have progressed rapidly and become among the main sources of power generation in the world. In the contribution “AIR-PV: a benchmark dataset for photovoltaic panel extraction in optical remote sensing imagery”, Yan et al. propose a large-scale benchmark dataset, namely AIR-PV, for photovoltaic panel extraction in RS imagery. The main features of this benchmark dataset are: (1) large-scale with wide distribution across five provinces of western China to cover a wide range of geographical styles and background diversity, covering more than 3 million square kilometers with more than 300,000 photovoltaic panels; (2) one of the earliest publicly available datasets (https://github.com/AICyberTeam) for photovoltaic panel extraction, providing a standard data foundation for applying advanced deep learning technology to photovoltaic panel extraction in remote sensing, thereby promoting various social applications related to photovoltaic power.

In the last contribution, “Multi-layer composite autoencoders for semi-supervised change detection in heterogeneous remote sensing images”, Shi et al. develop concise multi-layer composite autoencoders for change detection in heterogeneous remote sensing images, which avoid complex alignment or transformations in the traditional change detection frameworks, which only require 0.1% of true labels (approaching the cost of unsupervised models).
